Data on cyclists is limited: Small and dispersed group Missed in traffic counts Agencies lack funds earmarked for bicycle counts Frequent use of stated preference surveys Cycling models are inadequate: Included in demand models as an approximate percentage of total demand Trip distribution and mode choice often ignores cyclists Route choice models do not consider preference variation based on demographics
Most of Atlanta s bicycle network miles have a level of service ranking of E or worse 1 7/8/2014 Misra,Watkins,LeDantec 7
There is a lack of data on the state of bicycle infrastructure in Atlanta Half of trips made are < 3 miles, but only 1.8% of those trips are made by bike 2 Cycling can reduce greenhouse gas emission, congestion and provide healthy lifestyle 3 Cyclists prefer dedicated infrastructure 4 Involve citizens to get bicycle data to inform infrastructure decisions 7/8/2014 Misra,Watkins,LeDantec 8
How can we achieve this?
Crowdsourcing! Greater public participation Removes location and time constraint Diverse stakeholder involvement Anonymous participation option Ideal for dispersed user base Less cost intensive than traditional methods MORE DATA FOR BETTER PLANNING!! 7/8/2014 Misra,Watkins,LeDantec 10
Crowdsourcing System Components: Problem: Data Collection/User Feedback Our Project Organizer: City of Atlanta, Atlanta Regional Commission, Georgia Tech Participants: Local Cyclists Platform: Smartphone based 7/8/2014 Misra,Watkins,LeDantec 11
Our Precursor: Cycle Tracks, San Francisco 7/8/2014 Misra,Watkins,LeDantec 12
What did we develop?
Two New Components of Data Collection 1. Demographics 2. Issues and Assets 7/8/2014 Misra,Watkins,LeDantec 15
Cycle Atlanta: Demographic Categories Age Gender Ethnicity Home Income Less Than 18 Male White Less than $20,000 18-24 Female African American $20,000-$39,999 25-34 Asian $40,000-$59,999 35-44 Native American $60,000-$74,999 45-54 Pacific Islander $75,000-$99,999 55-64 Multi-racial $100,000 or greater 65+ Hispanic/Mexican/Latino Other Cycle Frequency Daily Several times per week Several times per month Less than once a month Rider History Since childhood Several years One year or less Just trying it/just started 7/8/2014 Misra,Watkins,LeDantec 16
Rider Type Strong and fearless Enthused and Confident Comfortable, but cautious Interested, but concerned
Assets Cycle Atlanta Data Collection + Bike parking + Bike shops or repair kits + Public restrooms + Secret passage + Water fountains Issues Pavement issue Traffic signal Enforcement Bike parking Bike lane issue Framework: Infrastructure
